Prenatal Hormone Levels Linked to Gestational Diabetes Risk

Among that group, 256 women developed gestational diabetes during pregnancy and 497 did not.

The investigators examined examine whether circulating total and high–molecular weight (HMW) adiponectin concentrations, measured before pregnancy, are associated with subsequent risk of gestational diabetes mellitus (GDM). They found that normal-weight women with low levels of adiponectin were 3.5 times more likely to develop gestational diabetes than their normal-weight peers with normal levels of the hormone.

Additionally, overweight women with high levels of adiponectin were 1.7 times as likely to develop gestational diabetes during pregnancy, while those with the lowest levels were 6.8 times more likely. The combined effects of having total adiponectin levels below the median of less than 10.29 mg/mL and being overweight or obese were associated with a sevenfold increased risk of GDM compared with normal-weight women with adiponectin levels above the median.

Monique M. Hedderson, PhD, the principal investigator of the study, said, “Our findings indicate important pregnancy interventions may be possible before a woman even conceives. Adiponectin levels are easy and inexpensive to measure and could potentially be used to identify women who are at risk for gestational diabetes." The study was published on August 29, 2013, in the journal Diabetes Care.
